TELEPHONE ATTACHMENT.

Application filed J'u1y'29,

The principal objects and advantages of my invention are the provision to a greater degree,'in a telephone attachment, of:

1. Ample means for Writing, and for referring to, such data as are usually desired, or either, while using the telephone;

2. Means which shall amply provide for writing and for referring to such data as *are usually desired, or either, while using the telephone, and which is not in the way when the telephone or said means is not in use;

3. Means of each :and all of the above mentionedcharacteristics which "shall be simple to operate while using the telephone.

The-first object is accomplished in part by"having an element or elements of a telephone instrument or attachment which can be moved easily away from and back to 1ts normal position. Such element or elements are also so designed that they can hold both writing'and referenceunatcrial or either. This'p'rinciple is carried out in the llustrationused," by'a member designed to'be pivotedso it'c'an be swungfrom approximately a verticl positionto "approximately a hori zontal position, and to be placed so as to'be out of the way when not in use. Thus this principle'provides greater available working surface in'proportion' to the space taken up when in its normal and operating position, and also makes it possible to place the attachment in'a more appropriate place.

Thesecond object is accomplished in part by the principle of designing the elements of" a'telephone attachment so that the principal ClllllEllSlOllS or characteristic outline tlier'eofarerelatively similar to the dimensions or characteristic outline OfSOIllG part of the telephoneinstrument and so that it' can "be so'placed in relation to the partor parts'ofthe telephone instrument that it takesup no space that is not ElliOWGthfOllH 5 the-usualhandling of the telephone lnstrument' itself, the same in this respect as though these mea'ns' were integral. with a telephone instrument'ot' the usual design; andit also retains th'e'otheressential' characteristics of a useful devicelofrthis class. This principle isifulfi-lledrin the illustrationfselectedby. the designing'of a complete attachment, in its normal position, of a' length approximately the-same as the standard. of. the telephone 1922. Serial No. 578,426.

instrument and of a width not great enough to interfere with the usual handling" of the instrument, and adapted to be placed near the said'standard.

The third result or object iscarr'ied out in part by' the placing of the attachment designed upon the foregoing principles near the standard and by'use of the pivoted element so that the movement; of the hand or finger from the phone instrument Will swing down the pivoted element, and this element \vill'automatically return to its 'normal posiples is shown in the drawings and are thus explained:

Figure I shows the attachment complete and fixed to a telephone HlStIUDIGIlt; Figure II shows one of the two principal members of the attachment which is'numbered 1.' Figure III shows the other principal member of the attachment which is numbered 7, and also the spring numbered 14: which actuates'thls member. Figure IV shows member numl'iered 15 and the manner ofin's'erting the ends thereof'into the composed of a flat piece of metal. Its sides #2 and #3 are bent at right angles to the -'main' surfaceo'f the member. The lower end #of said member is grooved on the same sideof the main surface of said member on which sides #2 and #3 are bent. member is proportioned'so' that it can-be placed against the standard'of a telephone instrument and no parttof it extend beyond the base of said instrument or take up more space than is generally allowed inhandling This Fill

till

said instrunuxnt.

lo the lower portions oli sides and :frfzti are cut holes #1:?) and 55th placed so that rivets or other me us of PLTOiJ- ing another member thereto may be placed through them.

The member alt? composed of a hat piece of metal. it sides and :tjztl are bent at right angles to the main sun-taco of said member. The outside width of member it? is slightly less than the inside width of member .glgl'l so that member .q'iri' will titinside (it the sides of member #1 throughout the length thereof. The lower end of said member bent back against the main surface thereof in a curve between the two sides of #8 and qES), and is numbered 10.

In the lower portions o'l. sides #8 undid-f.) are cut holes :lqfrll and :l i'lll in relative position to the two holes and 6 in member git-l. Rivets are placed through the hole in member #1 and hole #1 511 in member :7 and through hole :htii in member and hole #:6 in membei .;:1, thus holding;- those two members in a pivoted position.

A piece ol flat spring steel girl-l is attached to both members t l-l and :ttl'. A piece oi metal #15 is bent longitudinally so that its two edg s lie against each other and the ends of said piece are bent to form round longitudinal extensions at both ends which lit into small holes numbered ltrin the lower part of sides S and it) ot member :l L-T near the base thereof where said sides are bent in slightly. One edge oi said spring is inserted between the edges of said piece 5. The opposite edge of said spring is inserted into the grooved end l of member it'l thus closing the space between the ends of member gtfcl at aftl and ot' member it! at #10.

On member git-.1 is also out two narrow lingers or rings #18 and s lt) which are bent outwardly between the sides of said member and form an arc.

(in member girl in each side :tlzi] and thereof is cut a. strip or finger #90 and :lis'l. which is bent inwardly. These strips are cut awati-om the member tor a short distance in From the sides so as to give it greater spring rpialitics when certain metals are used.

in operation writing or reference material is tastcned in member :lrtl' under the end :tlcltl thereoi ll ritiugy; or reference material is placed. also in member #1 by pulling said member down an extra distance so that the ends of rings #18 and #19 will be a distance away from the bent lower end :10 of member 7 and inserting the circular fingers or rings git-18 and #19 through holes provided in such material. here separate sheets of such material are used it is advisable that the outside sheet be relatively still to better resist wear at the edges by the strips #520 and #21.

Upon drawing member #7 up to approximately a horizontal position the spring I JfI l/l; press and twists outwardly and upwardly against, the lower and ot this member between the holes =2: 16 and forces the other end of same upwaii and inward and close to member i'cl. Both the pressure oi? spring in straightening: itself and the more local pres sure where piece .,;i;i5 presses against a particular portion ot the arc of the COlllPl'Gt'SSQtl spring when said piece tlfi is held against member gigs? at as is particularly shown in Figure V, is utilized. The sides tti and thereot being pivoted on inside oi. sides and will eoi'npletely close against the material inserted in the attacl'mieut.

lluis the two members will he automatieally closed against one another and remain so until member is again drawn down close to the table on which the inst ument rests when the index sheets or other inaterial in member #1 will remain up by reason or the strips or lingers :llrlfi and g :21 in each side oi said member pressil'lp; against the sides 0'! the sheets therein or any part of same which is not purposely pulled down. The mcinorarda pad or other material in n'iember sit-T will also be revealed in an approximately horizontal position atthe same time. When member i-T approaches close to the table the action of the spring reverses and mores said member down to the limit ol' its movement, by reason at the prez-rnrc of said spring in straightening it.- selt passing the line of the pivoted ccilter sutlicient to overcome the pressure of piece against the arc of the compressed spring". is pulled above ill'l'lllill': ment has its lona'iludiual edges bent at an angle appropriate to receive the edges ot flanges #22 and 2533). A. screw passes through each iiaug e. and with a nut thereon tightens the said flanges and collar around and agraiust. the standard. ".lhe lower part. of the flanges #22 and #23 is wider than the upper part which causes the attachment to tilt away from the standard at the bot tom sufficient for the lingers to be inserted between member and the standard of the telephone instrument, and also to cause the movable paper inserted in member :ttl to rest back against said member #1.

It is contemplated to apply these principles or a part of same to provide an attachment solely for writing purposes or solely for reference purposes, as well as for the combination of both.

Where the word attachment is used, particularly in the claims, it is used as meaning any part of a telephone system; and contemplates forming an integral part of a telephone receiving and sending instrument, or a separate unit applied thereto such as on a desk instrument or on a switchboard, except where specifically limited to one of the above purposes.

I claim 1. The combination, in ';a telephone attachment, of a member the side edges or portions of which are at approximately right angles to the main surface thereof and adapted to hold the bottom portions of cards between said sides so that same may be swung outwardly from the top thereof, and a second member, adapted to hold paper, attached movably to said first member and lying normally adjacent to the edges of the sides of the first member.

, 2. The combination, in a telephone attachment, of a member the side edges or portions of which are at approximately right angles to the main surface thereof and adapted to hold the bottom portions of cards between said sides so that same may be swung outwardly from the top thereof, and attached vertically to the upright member of a telephone instrument, and a second member, adapted to hold paper, attached movably to said first member, and means to automatical- 1y move the second member through a desired portion or portions of its prescribed movement.

3. The combination, in a telephone attachment, of a member with flat sides at approximately right angles to the main surface thereof and rings on the lower portion of said member so paper attached to said rings may be moved in an are away from said member at the top thereof, and a second member, adapted to hold paper, attached movably to said first member at the flat sides thereof.

4;. The combination, in a telephone attachment, of a member with flat sides at approximately right angles to the main surface thereof and adapted to hold paper, and a second member with flat sides at right angles to the main surface thereof adapted to hold paper and attached movably to said 1first member at the flat sides of each mem- 5. The combination, in a telephone attachment, of a member with flat sides and adapted to hold the lower edges of cards on the lower portion of said member so the top of said cards can ,be swung outwardly, and adapted to be attached vertically to the principal upright member of a telephone instrument, and a second member with flat sides and adapted to hold paper, and attached movably to said first member at the flat sides of each member, and means to automatically move said second member through a desired portion or portions of its prescribed movement.

6. The combination, in a telephone attachment, of a movable member and a spring adapted to actuate said member by the pressure caused by the ends of the compressed spring in straightening itself and also by the lateral pressure of the bending portion of said compressed spring as said bending portion presses against the edge of said movable member.

7. The combination, in a telephone attachment, of a movable member and a spring adapted to move said member in one direction by the pressure of the ends of said spring in straightening itself and by the lateral pressure of the arc of the compressed spring as said are is forced against the edge of said movable member, and in another direction by the pressure of the end of said spring as it moves past the line between the center of the pivot of said movable member and the stationary end of said spring, thus overcoming the pressure of the arc of the compressed spring.

8. The combination, in a telephone attaclnnent, of a member bent longitudinally so that its opposite longitudinal edges approximately meet and round projections at each end thereof adapted to fit eccentrically and semi-rotatably into a movable member, and a flat spring one end of which is adapted to be held in said semi-rotatable member and the opposite end of said spring adapted to be held in a stationary member to which the movable member is connected so that said spring will be bent so as to counteract the movement of said movable member.
